For some users - cPanel's incremental backup feature can sometimes cause a bit of confusion. One thing to remember is that when you set cPanel to do incremental backups (Daily, Weekly and Monthly) - it only keeps one instance of each state. In other words, if you were looking to restore from 4 days ago, you would have the options of going with the most recent daily or weekly backup.

For those looking, the backups are located in your /backup dir (VPS/DED Users Only).
